The Condition"Pulmonary embolism is a severe and life-threatening condition, caused when the pulmonary artery is blocked by foreign matter such as a blood clot (thrombus), fat, air or tumor tissue..." Our Question about a cough that produces mucus"A cough that begins suddenly, sometimes mixed with blood-streaked sputum, is a frequently-seen symptom of pulmonary embolism, but other symptoms are more likely to point to the correct diagnosis..."

Lodging of a blood clot in the lumen (open cavity) of a pulmonary artery, causing a severe dysfunction in respiratory function. Pulmonary emboli often originate in the deep leg veins and travel to the lungs through blood circulation. Symptoms include sudden shortness of breath, chest pain (worse with breathing), and rapid heart and respiratory rates.

The obstruction of the pulmonary artery or a branch of it leading to the lungs by a blood clot, usually from the leg, or foreign material causing sudden closure of the vessel. (Embolus is from the Greek "embolos" meaning plug.) See the entire definition of Pulmonary embolism

cardiology The lodgment of a blood clot in the lumen of a pulmonary artery , causing a severe dysfunction in respiratory function . - Pulmonary emboli often have origin in the veins of the lower extremities where clots form in the deep leg veins and then travel to the lungs via the venous circulation . - Symptoms and features include acute onset of shortness of breath , chest pain ( worse with breathing ) and rapid heart rate and respiratory rate . Some individuals may have haemoptysis . Diagnosis can be made on a ventilation perfusion scan of the lung or on a pulmonary angiogram .

A potentially fatal blood clot that travels to the lungs, blocking major arteries. The risk for pulmonary embolism increases after surgery or prolonged bed rest. uickening: A woman's first experience of fetal movement. Quickening usually occurs between 16 and 20 weeks of pregnancy. h factor: A group of antigens present in the red blood cells.

A blood clot from a deep vein, usually in the legs, pelvis, or arms, that breaks loose and travels through the veins and then through the heart to lodge in the blood vessels in the lung. Large pulmonary emboli can be life-threatening and may need to be treated with fibrinolytic therapy, such as tPA (referred to as "clot-busters").

Obstruction or closing of pulmonary (relating to the lungs) arteries, most frequently by detached fragments of a blood clot from a leg or pelvic vein, commonly when the formation or presence of a clot has followed an operation or confinement to bed.

Pulmonary embolism is a blockage of an artery in the lungs by a blood clot, fat, air or clumped tumor cells. By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs.
